Kohler Engines introduced a number of new engines at The Rental Show recently in Las Vegas. To begin, Kohler partnered with Italy-based Lombardini to create the enhanced KD440 air-cooled, single-cylinder diesel. The redesigned model has been updated to offer improved performance and reduced maintenance costs. Key performance-improving upgrades include a new air filter, a modified tank, a new drain tap, and an updated recoil pulley.
The updated KD440 was specially designed to extend the time between maintenance intervals. Specific features that help make this possible include a redesigned air filter, an improved tank that helps reduce the entry of foreign particles and is easy to replace, and a new drain tap that allows for quick cleaning and simple replacement. A rubber-coated recoil pulley has also been integrated to reduce noise levels and improve operator comfort.
Kohler also showed Tier 4 Final emission-compliant, heavy-duty diesel engines for the industrial, construction and agricultural markets. The 1.9-liter KDI1903TCR and the 2.5-liter KDI2504TCR engines offer optimized fuel consumption, limited emissions and strong performance without the use of a diesel particulate filter. Through the efficient use of the engine’s components, including Kohler’s direct-injection system, cooled exhaust gas recirculation and diesel oxygenated catalyst, the company was able to meet the emissions standards.
Next on the Kohler parade of engines was its Command Pro CARB-compliant engine option, incorporating a secondary air injection system to meet the standards. Kohler’s SAI system injects air into the engine’s exhaust manifold to significantly minimize pollutants and enhance overall engine performance. The engine is designed for a range of commercial applications including agricultural tractors, lawn tractors, pumps, rollers, generators and other power equipment. The engines are available in horizontal and vertical configurations.
Kohler also introduced gear reduction options for rental industry professionals with reduced revolutions per minute speed while increasing torque. Kohler also introduced electronic fuel injection technology with the benefits of propane. The Kohler Command Pro EFI propane engine is an environmentally friendly option that lowers operating costs for landscape contractors. The new propane engine is an option on Kohler’s 23-and 27-hp commercial line.
